Economists often oppose the expansion of licensing in America in recent years because it makes it harder for people with low skills to get access to opportunity. Sociologist Beth Redbird of Northwestern University talks with EconTalk host Russ Roberts about a different perspective. Redbird finds that licensing expands opportunity for women and minorities and has little impact on wages. She argues that licensing helps historically disadvantaged groups discover ways into various careers they otherwise would have trouble accessing. The discussion closes with a discussion of Redbird's work on the economic situation of Native Americans.

Jordan Peterson, author of 12 Rules for Life, talks about the book with EconTalk host Russ Roberts. Topics covered include parenting, conversation, the role of literature in everyday life, and the relationship between sacrificial rites and trade.

What does the "sheepskin effect" tell us about earning a college degree? Does a college education buy more than a Grade A premium employee stamp?

Bryan Caplan discusses human capital, the ability bias, and the particular importance of signaling as the reason for the greater earnings of college graduates as compared to high school graduates. In questioning the difficulty of measuring the value of a college education, host Russ Roberts steers this week's conversation toward how we learn, some of the shortcomings of K-12 and college education, and how we apply what we learn in practical settings.

1. Given the value of signalling and the findings of the sheepskin effect, to what extent is a college education a waste of time and/or money? What other factors, such as the acquisition of the first post-college job in one's desired field, to their eventual career trajectory?

Bryan Caplan of George Mason University and the author of The Case Against Education talks about the book with EconTalk host Russ Roberts. Caplan argues that very little learning takes place in formal education and that very little of the return to college comes from skills or knowledge that is acquired in the classroom. Schooling, he concludes, as it is currently conducted is mostly a waste of time and money. Caplan bring a great deal of evidence to support his dramatic claim and much of the conversation focuses on the challenge of measuring and observing what students actually learn.

Tyler Cowen of George Mason University and the co-host of the blog Marginal Revolution talks with EconTalk host Russ Roberts about Stubborn Attachments, his book-length treatment of how to think about public policy. Cowen argues that economic growth--properly defined--is the moral key to maintaining civilization and promoting human well-being. Along the way, the conversation also deals with inequality, environmental issues, and education.

Martha Nussbaum, Professor of philosophy at the University of Chicago talks with EconTalk host Russ Roberts about Alexander Hamilton. Nussbaum talks about the tension between acquiring power and living a life of virtue. Topics discussed include Hamilton's relationship with Aaron Burr, Burr's complicated historical legacy, and the role of the humanities in our lives.

Author and legal scholar Cass Sunstein of Harvard University talks with EconTalk host Russ Roberts about his latest book, #Republic. Sunstein argues that the internet has encouraged people to frequent informational echo chambers where their views are reinforced and rarely challenged. In addition, there is a loss of public space where people might have to encounter dissonant ideas or causes they might wish to champion. Sunstein considers this a threat to democracy and discusses a variety of ways the situation might improve.

EconTalk host Russ Roberts welcomed back Doug Lemov, of Uncommon Schools, this week, for a very interesting conversation about reading, and especially, reading rigorously. In his new book, Reading Reconsidered, Lemov's primary audience is educators, but as Russ notes, and as should be evident from their conversation, it has relevance far beyond the classroom.

How much do you read today, and do you prefer electronic reading to "real" books? How has the digital age- and your cellphone, in particular- changed your reading habits? Those of your children and/or students? Do you ever read aloud anymore? Share your thoughts on this week's episode with us; we love to hear from you.

1. What does Lemov mean when he says that reading is "first among equals," and to what extent do you agree?

Doug Lemov of Uncommon School and co-author of Reading Reconsidered talks with EconTalk host Russ Roberts about reading. Lemov makes the case for the educational importance of critical reading of challenging books and texts. Along the way, he gives listeners some ideas of how to read themselves and gives parents some ideas for how to educate their children.

David Gelernter, professor of computer science at Yale University and author of The Tides of Mind, talks with EconTalk host Russ Roberts about consciousness and how our minds evolve through the course of the day and as we grow up. Other topics discussed include creativity, artificial intelligence, and the singularity.

Cathy O'Neil, data scientist and author of Weapons of Math Destruction talks with EconTalk host Russ Roberts about the ideas in her book. O'Neil argues that the commercial application of big data often harms individuals in unknown ways. She argues that the poor are particularly vulnerable to exploitation. Examples discussed include prison sentencing, college rankings, evaluations of teachers, and targeted advertising. O'Neil argues for more transparency and ethical standards when using data.

Are workers being left behind when the economy grows? Is technology making the human workforce obsolete? James Bessen, author of Learning by Doing, talks with EconTalk host Russ Roberts about the role of learning on the job in the past and in the present. Bessen argues that during times of technological innovation, it often takes years before workers see higher wages from productivity increases. Bessen stresses the importance of the standardization of education on the job as workers adapt to new technology.

Alison Wolf author of The XX Factor, talks with EconTalk host Russ Roberts about the changing roles of women in the family and the workplace. Wolf argues that highly educated women are increasingly similar to highly educated men in their lifestyles and choices while becoming very different from less educated women. Wolf traces the origins of these changes and the interaction between economic and cultural factors affecting men, women, the family, and the workplace.

How can you learn to think like an economist? One way is to think about what might be called dinner table economics--puzzles or patterns that arise in everyday life that would be good to understand. Robert Frank of Cornell University and author of The Economic Naturalist talks with EconTalk host Russ Roberts about a number of these puzzles including why grooms typically rent tuxedos but the bride usually buys her gown, why bicycles can be more expensive to rent than cars, the effects of the price of corn on the price of pork, and why scammers who invoke Nigeria keep using the same old story.

Michael Munger of Duke University makes his 29th appearance on the 500th episode of EconTalk alongside EconTalk host Russ Roberts. He talks about his personal intellectual journey, his interest in public choice, and Unicorn economics. Other topics include the origins of EconTalk, Roberts's intellectual roots, and the EconTalk theme music. The conversation closes with a brief reprise of a few highlights from past Munger appearances on EconTalk.

What did you think of this week's episode? What did it make you think more about? Share with us your thoughts and reactions, helping us make EconTalk ever better. As always, we learn from you and we love to hear from you.

1. What additional question(s) would you have asked Hanushek?

2. Hanushek suggests a causal relationship between academic achievement and economic growth in a nation, What is the nature of Russ's concern about "reverse causation?" To what extent do you find Hanushek's claim plausible?

How important are basic skills for economic success and growth? Eric Hanushek of Stanford University's Hoover Institution talks with EconTalk host Russ Roberts about the importance of basic education in math and literacy and their relationship to economic growth. Hanushek argues that excellence in educating people in basic skills leads to economic growth, especially in poorer countries where years of education may be a poor proxy for learning. He argues that the U.N.'s Millennium Development Goals should emphasize outputs rather than inputs--performance on skill-based exams rather than years of education.

Nobel Laureate Alvin Roth of Stanford University talks with EconTalk host Russ Roberts about his work on matching markets. Examples include marriage, matching kidney donors to kidney recipients, and students to schools in cities that allow choice in their public school systems. Roth also discusses repugnance--the unease some people have with allowing buying and selling of some goods and what it's like to watch a kidney transplant knowing your research has helped make the surgery possible.

Luigi Zingales of the University of Chicago talks with EconTalk host Russ Roberts on whether the financial sector is good for society and about the gap between how banks and bankers are perceived by the public vs. finance professors. Zingales discusses the costs and benefits of financial innovation, compares the finance sector to the health sector, and suggests how business education should talk about finance to create better behavior.

This week, EconTalk host Russ Roberts welcomed author James Tooley to talk about what he discovered in researching the educational options of the world's poorest children. What he found is surprising to many, but as Roberts notes, some find Tooley's work dangerous. Let us know what you think about their conversation, using the prompts in this week's Extra.

James Tooley, Professor of Education at Newcastle University, talks to EconTalk host Russ Roberts about low-cost for-profit private schools in the slums and rural areas of poor countries. Tooley shows how surprisingly widespread private schools are for the poor and how effective they are relative to public schools where teacher attendance and performance can be very disappointing. The conversation closes with whether public schooling should remain the ideal in poor countries.

Daphne Koller of Coursera talks with EconTalk host Russ Roberts about online educational website Coursera and the future of education both online and via bricks-and-mortar. Koller, co-founder of Coursera with Andrew Ng, explains how Coursera partners with universities, how they try to create community and interaction, and the likely impact of widespread digital education on universities and those who want to learn. The conversation includes a discussion of why Koller left a chaired position in computer science at Stanford University to run a for-profit start-up in a crowded field.

Edward Lazear of Stanford University talks with EconTalk host Russ Roberts about Gary Becker's innovative contributions to economics. The conversation opens with personal reminiscences by Lazear and Roberts. They then discuss Becker's application of economic principles to social phenomena such as discrimination, crime, education and the family along with Becker's overall approach to economic theory and measurement.

Andrew McAfee, Megan McArdle, and Lee Ohanian talk with EconTalk host Russ Roberts on the future of work. Recorded before a live audience at the 33rd Santa Barbara Economic Summit, the conversation begins with each participant making a brief set of remarks on the topic. Topics discussed include the traits that might be rewards in a world of smart machines, reforming the educational system to prepare people for the changing economy, reforming immigration, and policies that might help the labor market work more effectively.

In this week's episode, Roberts talks with EconLog blogger Bryan Caplan about higher education. In the spirit of continuing conversation, here are some things to consider. As always, we love to hear from you!

Bryan Caplan of George Mason University and blogger at EconLog talks to EconTalk host Russ Roberts about the value of a college education. Caplan argues that the extra amount that college graduates earn relative to high school graduates is misleading as a guide for attending college--it ignores the fact that a sizable number of students don't graduate and never earn that extra money. Caplan argues that the monetary benefits of a college education have a large signaling component rather than representing the value of the knowledge that's learned. Caplan closes by arguing that the subsidies to education should be reduced rather than increased.

John Cochrane of the University of Chicago talks to EconTalk host Russ Roberts about the experience of teaching a massive open online course (MOOC)--a class delivered over the internet available to anyone around the world. Cochrane contrasts the mechanics of preparing the class, his perception of the advantages and disadvantages of a MOOC relative to a standard in-person classroom, and the potential for MOOCs to disrupt traditional education.

I've noticed in recent years that many of you want to get more out of EconTalk than just listening an hour each week. You want to go deeper and learn more. So we're starting a new feature here, EconTalk Extras, to try to enrich the learning experience of EconTalk. It will also be a way for me to interact with you beyond our weekly hour together and beyond FaceBook and Twitter.

We're going to start with some variety. Sometimes, I'll be doing a post-mortem on an episode, and possibly responding to some of the comments you've made. Other times we'll have discussion questions for you to react to or write about or just think about if you're interested. We have other ideas that we'll introduce as we go along.

I'll be producing some of this material and some will be produced by educators and staffers from Liberty Fund, the sponsor of EconTalk. They'll introduce themselves with their first post and every post will be identified by author.

We hope this new material makes EconTalk a richer educational experience. Let us know what you think. We'd love to hear other ideas as well.

Doug Lemov of Uncommon Schools and author of Teach Like a Champion talks with EconTalk host Russ Roberts about teaching and education. Drawing on his experience working in charter schools with children in poverty, Lemov discusses what makes a great teacher and a great school. Lemov argues that practice and technique can transform teaching and education. The conversation concludes with a discussion of how EconTalk might be made more valuable to its listeners.

Lant Pritchett of Harvard University and author of The Rebirth of Education talks with EconTalk host Russ Roberts about the ideas in the book. Pritchett argues that increases in years of schooling for students in poor countries do not translate into gains in education, learning, or achievement. This tragic situation is due to corruption and poor incentives in the top-down educational systems around the world. School reforms that imitate successful systems fail to take into account the organic nature of successful school systems that cause various external attributes to be effective. The conversation concludes with a discussion of school systems in rich countries and possible lessons for reform that might apply there.

John Ralston Saul, author and head of PEN International, speaks with EconTalk host Russ Roberts about his book, Voltaire's Bastards, and the role of reason in the modern world. Saul argues that the illegitimate offspring of the champions of reason have led to serious problems in the modern world. Reason, while powerful and useful, says Saul, should not be put on a pedestal above other values including morality and common-sense. Saul argues that the worship of reason has corrupted public policy and education while empowering technocrats and the elites in dangerous and unhealthy ways.

Tyler Cowen of George Mason University and blogger at Marginal Revolution talks with EconTalk host Russ Roberts about his latest book, Average is Over. Cowen takes a provocative look at how the growing power of artificial intelligence embodied in machines and technologies might change labor markets and the standard of living. He tries to predict which people and which skills will be complementary to smart machines and which people and which skills will struggle.

Eric Hanushek of Stanford University's Hoover Institution talks with EconTalk host Russ Roberts about his new book, Endangering Prosperity (co-authored with Paul Peterson and Ludger Woessmann). Hanushek argues that America's educational system is mediocre relative to other school systems around the world and that the failure of the U.S. system to do a better job has a significant negative impact on the American standard of living. Hanushek points to improving teacher quality as one way to improve education.

Edward Glaeser of Harvard University and author of The Triumph of Cities talks with EconTalk host Russ Roberts about American cities. The conversation begins with a discussion of the history of Detroit over the last century and its current plight. What might be done to improve Detroit's situation? Why are other cities experiencing similar challenges to those facing Detroit? Why are some cities thriving and growing? What policies might help ailing cities and what policies have helped those cities that succeed? The conversation concludes with a discussion of why cities have such potential for growth.

Jeffrey Sachs of Columbia University and author of The Price of Civilization talks with EconTalk host Russ Roberts about the state of the American economy. Sachs sees the current malaise as a chronic problem rather than a short-term challenge caused by the business cycle. He lists a whole host of issues he thinks policymakers need to deal with including the environment, inequality, and infrastructure. He disagrees with the Keynesian prescriptions for stimulating the economy and believes that the federal government budget deficits are a serious problem. The conversation closes with a discussion of the state of economics.

Peter Boettke of George Mason University talks with EconTalk host Russ Roberts about his book, Living Economics. Boettke argues for embracing the tradition of Smith and Hayek in both teaching and research, arguing that economics took a wrong turn when it began to look more like a branch of applied mathematics. He sees spontaneous order as the central principle for understanding and teaching economics. The conversation also includes a brief homage to James Buchanan who passed away shortly before this interview was recorded.

Arnold Kling, economist and teacher, talks with EconTalk host Russ Roberts about recent technological innovations in education and Kling's forecast for their impact on learning and how they might affect traditional education. Examples include the recent explosion of online lessons and classes, new teaching styles that exploit those offerings, and the nature of learning in various kinds of classrooms and student-teacher interactions.

Paul Tough, author of How Children Succeed, talks with EconTalk host Russ Roberts about why children succeed and fail in school and beyond school. He argues that conscientiousness--a mixture of self-control and determination--can be a more important measure of academic and professional success than cognitive ability. He also discusses innovative techniques that schools, individuals, and non-profits are using to inspire young people in distressed neighborhoods. The conversation closes with the implications for public policy in fighting poverty.

Brian Nosek of the University of Virginia talks with EconTalk host Russ Roberts about how incentives in academic life create a tension between truth-seeking and professional advancement. Nosek argues that these incentives create a subconscious bias toward making research decisions in favor of novel results that may not be true, particularly in empirical and experimental work in the social sciences. In the second half of the conversation, Nosek details some practical innovations occurring in the field of psychology, to replicate established results and to publicize unpublished results that are not sufficiently exciting to merit publication but that nevertheless advance understanding and knowledge. These include the Open Science Framework and PsychFileDrawer.

Roger Noll of Stanford University talks with EconTalk host Russ Roberts about the economics of sports. Noll discusses the economic effects of stadium subsidies, the labor market for athletes, the business side of college sports, competitive balance in sports leagues, safety in sports, performance-enhancing drugs, and how the role of sports in the lives of children has changed.

Enrico Moretti of the University of California, Berkeley and the author of the New Geography of Jobs talks to EconTalk host Russ Roberts about the ideas in his book. Moretti traces how the economic success of cities and the workers who live there depends on the education of those workers. Moretti argues that there are spillover effects from educated workers--increased in jobs and wages in the city. He uses changes in the fortunes of Seattle and Albuquerque over the last three decades as an example of how small changes can affect the path of economic development and suggests a strong role for serendipity in determining which cities become hubs for high-tech innovation. The conversation concludes with Moretti making the case for increasing investments in education and research and development.

Jonah Lehrer, staff writer for The New Yorker and author of Imagine: How Creativity Works, talks with EconTalk host Russ Roberts about the science of creativity. They discuss focusing vs. ignoring as a way to solve problems, the potential for computer-based creativity, how W. H. Auden used drugs to improve his poetry, Bob Dylan, Steve Jobs, and the creative power of mindless relaxation. The conversation closes with a discussion of what policies might increase creativity.

David Owen, author of The First National Bank of Dad, talks with EconTalk host Russ Roberts about how to educate our children about money and finance. Owen explains how he created his own savings accounts for his kids that gave them an incentive to save and other ways to teach them about postponing gratification, investing, keeping money in perspective and other life lessons. The conversation closes with a discussion of the value of reading to your kids.

Adam Davidson of NPR's Planet Money talks with EconTalk host Russ Roberts about manufacturing. Based on an article Davidson wrote for The Atlantic, the conversation looks at the past, present, and future of manufacturing. Davidson visited an after-market auto parts factory in Greenville, South Carolina and talked with employees there as well as with executives at corporate headquarters. What is the future of factory work in America? Why are some manufacturing jobs in America while others are in China or elsewhere? The conversation looks at these questions as well as how well or poorly the U.S. education system prepares students for the world of work.

Alex Tabarrok of George Mason University talks with EconTalk host Russ Roberts about his new book, Launching the Innovation Renaissance. Tabarrok argues that innovation in the United States is being held back by patent law, the legal system, and immigration policies. He then suggests how these might be improved to create a better climate for innovation that would lead to higher productivity and a higher standard of living.

Eric Hanushek of Stanford University's Hoover Institution talks with EconTalk host Russ Roberts about the importance of teacher quality in education. Hanushek argues that the standard measures of quality--experience and advanced degrees--are uncorrelated with student performance. But some teachers consistently cover dramatically more material and teach more than others, even within a school. Hanushek presents evidence that the impact of these differences on lifetime earnings for students can be quite large. The conversation closes with a discussion of school finance and the growth of administrators within school systems.

Abhijit Banerjee of MIT talks with EconTalk host Russ Roberts about Banerjee's book (co-authored with Esther Duflo), Poor Economics. The conversation begins with how randomized control trials (a particular kind of social experiment) have been used to measure the effectiveness of various types of aid to the poor. Banerjee goes on to discuss hunger, health, and education--the challenges in each area and what we have learned about what works and what does not. The conversation closes with a discussion of the role of the labor market in the private sector.

William Byers of Canada's Concordia University and author of The Blind Spot talks with EconTalk host Russ Roberts about the nature of knowledge, science and mathematics. Byers argues that there is an inherent uncertainty about science and our knowledge that is frequently ignored. Byers contrasts a science of wonder with a science of certainty. He suggests that our knowledge of the physical world will always be incomplete because of the imperfection of models and human modes of thought relative to the complexity of the physical world. The conversation also looks at the implications of these ideas for teaching science and social science.

Daniel Pink, author of Drive, talks with EconTalk host Russ Roberts about drive, motivation, compensation, and incentives. Pink discusses the implications of using monetary rewards as compensation in business and in education. Much of the conversation focuses on the research underlying the book, Drive, research from behavioral psychology that challenges traditional claims by economists on the power of monetary and other types of incentive. The last part of the conversation turns toward education and the role of incentives in motivating or demotivating students.

Diane Ravitch of NYU talks with EconTalk host Russ Roberts about the ideas in her new book, The Death and Life of the Great American School System: How Testing and Choice Are Undermining Education. Ravitch argues that the two most popular education reform movements, accountability and choice, have had unintended consequences that have done great harm to the current generation of students. She argues that the accountability and testing provisions in legislation like No Child Left Behind and similar reforms have actually corrupted the testing process, taken time away from subjects other than math and reading, and failed even to boost success in math and reading. She argues that the empirical record has provided little evidence that school choice as it has been implemented has boosted achievement. The discussion closes with a discussion of what reforms might indeed make a difference.

Garett Jones of George Mason University talks with EconTalk host Russ Roberts about the art of communicating economics via puzzles and short provocative insights. They discuss Jones's Twitter strategy of posting quotes and short puzzles to provoke thinking. Jones, drawing on his experience as a Senate staffer, discusses the interaction between politics and economics in the area of tax cuts and earmarks. For example, are earmarks good or bad? Jones gives an unconventional analysis. He also discusses the economics of the new workplace and why that might mean a different path for productivity over the business cycle than in the past.

Nobel Laureate Michael Spence of Stanford University's Hoover Institution and the Commission on Growth and Development talks with EconTalk host Russ Roberts about the determinants of economic growth. Spence discusses the findings of the Commission's recent report and how it compares to earlier attempts to uncover the sources of growth and the lack of growth such as the Washington Consensus. Spence makes the case for government provision of infrastructure including education and the problems of corruption and governance. The conversation closes with a look at Spence's career and the lessons of that experience.

Mike Munger of Duke University talks with EconTalk host Russ Roberts about many things. Listeners sent in questions for Mike and Russ to talk about and they chose ten of the most interesting questions with the idea of talking about each for six minutes. The topics are the scarcity of clean water, asset bubbles, the role of Fannie and Freddie in the financial crisis, can a business pass a tax on to its customers (or maybe even its workers), compassionate food, the study of economics, how to choose a college, the nature of cooperation in a modern economy, the humanity of non-profits, and the American Dream.

Daniel Willingham of the University of Virginia and author of the book Why Don't Students Like School? talks with EconTalk host Russ Roberts about how the brain works and the implications for teaching, learning, and educational policy. Topics discussed include why we remember some things but not others (and what we can do about it), the central role of memory in problem solving and abstract reasoning, the current state of math education in America, and what makes a good teacher.

Eric Hanushek of Stanford University's Hoover Institution talks with EconTalk host Russ Roberts about the current state of education and education policy. Hanushek summarizes the impact of No Child Left Behind and the current state of the charter school movement. Along the way, he and Roberts discuss the role of testing as a way of measuring achievement. The conversation concludes with a discussion of school finance, the role of the court system, and suggestions for improving finance to create better incentives.

Ricardo Reis of Columbia University talks with EconTalk host Russ Roberts about Keynesian economics in the classroom and in research. Reis argues that Keynesian models are a useful framework for helping undergraduates understand macroeconomic ideas of general equilibrium. More generally, Reis argues, Keynesian ideas remain influential in macroeconomic research, particularly among Neo-Keynesians. Reis discusses the lessons the economics profession and the world have learned from the Great Depression and suggests that those lessons have helped us manage the current crisis. The conversation closes with a discussion of whether economics is a science.

George Srour, founder of Building Tomorrow, a non-profit that builds schools in Uganda, talks with EconTalk host Russ Roberts about his experience starting, funding, and running an organization that tries to change the world one school at a time. Srour discusses how he tries to make sure that his organization accomplishes more than bricks and mortar and the rewards and challenges of a start-up non-profit.

Hal Varian, Google's Chief Economist and University of California at Berkeley professor, talks with Russ Roberts about Google, the role of technology in our everyday lives, the unintended paths of innovation, and the value of economics.

Eric Hanushek of Stanford University's Hoover Institution talks with EconTalk host Russ Roberts about the strange evolution of school finance in the last four decades. In particular, the courts have played an important role in recent years in mandating expenditure increases for public school systems. Hanushek talks about why this has come about and the lack of effect these expenditures have had in affecting student achievement.

Daniel Botkin, ecologist and author, talks with EconTalk host Russ Roberts about how we think about our role as humans in the natural world, the dynamic nature of environmental reality and the implications for how we react to global warming.

Author Robert Frank of Cornell University talks about economic education and his recent book, The Economic Naturalist. Frank argues that the traditional way of teaching economics via graphs and equations often fails to make any impression on students. In this conversation with host Russ Roberts, Frank outlines an alternative approach from his new book, where students find interesting questions and enigmas from everyday life. They then try to explain them using the economic way of thinking. Frank and Roberts discuss a number of the enigmas and speculate on the future of economics and education. The topics discussed include tuxedos vs. wedding dresses, the level of civility (or lack thereof) in New York City, the difference between vending machines for soda and newspapers, the tragedy of the commons, and the economics of love.

Hoover Institution Senior Fellow Eric Hanushek talks about his research on the impact of educational quality on economic growth. Past efforts to increase the economic growth rate of poor countries have focused on years of schooling, neglecting the quality and true education that needs to take place. Hanushek presents dramatic findings about the decisive nature of cognitive ability and knowledge in driving economic growth. Join us as Hanushek talks with EconTalk host Russ Roberts about his findings and the implications for public policy around the world and in the United States.

David Henderson, editor of the Concise Encyclopedia of Economics and a research fellow at Stanford's Hoover Institution, talks with EconTalk host Russ Roberts about when and why economists disagree. Harry Truman longed for a one-armed economist, one willing to go out on a limb and take an unequivocal position without adding "on the other hand...". Truman's view is often reflected in the public's view that economic knowledge is inherently ambiguous and that economists never agree on anything. Henderson claims that this view is wrong--that there is substantial agreement among economists on many scientific questions--while Roberts wonders whether this consensus is getting a bit frayed around the edges. The conversation highlights the challenges the everyday person faces in trying to know when and what to believe when economists take policy positions based on research. Is it biased or science?

Author David Weinberger, a fellow at Harvard's Berkman Institute for Internet and Society, talks with EconTalk host Russ Roberts about the ideas in his latest book, Everything is Miscellaneous: The Power of the New Digital Disorder. Topics include the differences between how we organize and think about physical and digital information, the power of the internet to let us consume information in unique and customized ways and the implications for retailing, politics and education.

Author Dan Pink talks about the ideas in his book, A Whole New Mind: Why Right-Brainers Will Rule the Future. He argues that the skills of the right side of the brain--skills such as creativity, empathy, contextual thinking and big picture thinking--are going to become increasingly important as a response to competition from low-wage workers overseas and our growing standard of living.
